In this video, we break down the concept of Nitrogenous Biochemical Oxygen Demand (NBOD) — the oxygen consumed during nitrification, when microorganisms convert ammonia (NH₃) into nitrate (NO₃⁻). Learn how NBOD differs from Carbonaceous BOD (CBOD), which involves the oxidation of organic carbon compounds, and how both together form the Ultimate BOD (BOD₍ᵁ₎).
We’ll also explore why NBOD is so important in wastewater treatment and aquatic ecosystem management, highlighting its role in dissolved oxygen (DO) depletion — a serious issue for aquatic life. Plus, discover how scientists calculate the Theoretical Nitrogenous Oxygen Demand (ThNOD) and measure NBOD in the lab using inhibited and uninhibited BOD tests.
If you’re a student, operator, or environmental professional looking to better understand the biochemical processes behind water quality, this video is for you!
